Quote of the day No 150

Friday 3 July 2015

The pound-lockóby which you can raise or lower craft from one level to another by means of a kind of cistern capable of being filled or emptied and entered through gates at either endówas apparently just one more invention of that extraordinary genius Leonardo da Vinci, which he applied in the Mortesana Canal built to supply Milan with water round about the year 1488. It was not used in England until 1563 in the Exeter Canal, and even then was not applied on a large scale until the Canal Era opened in the second half of the 18th century. On the Thames, the first pound-locks were erected in the middle of the 17th century during the reign of James I between Burcot and Oxford.

Before that, so-called locks had been used on the river for centuries, but they were not locks in our sense of the word but merely rough staunches or weirs lying across the stream, made of closely spaced timber stakes filled with chalk and stones. These stemmed back the water at certain points, sometimes to intercept fish, sometimes to create a head of water for milling and sometimes to create a floating depth for navigation.

Eric de Mare Time on the Thames
